PyroUSB PC Configurable Non-Contact Temperature Sensor with 4 to 20 mA Output * Configurable temperature range, emissivity setting etc. from a PC via CalexSoft software and USB cable (supplied) * Features max; min; average and instantaneous readings; peak or valley hold; reflected energy compensation * OPC Server capabilities * Temperature range -40 to 1000C * Emissivity: 0.1 to 1.0 * Response time: 240 ms to 90% * Stainless steel housing, sealed to IP65 * Field of view: 15:1, 30:1 or Close Focus * 4 to 20 mA output * Quick and easy installation * Optional air/water cooled housing, air purge collar, laser sighting tool and mounting brackets Power Supply Red + - The PyroUSB Series measures temperatures from -40C to 1000C accurately and consistently, with an outstanding response time of 240 ms. The 4 to 20 mA output is compatible with almost any indicator, controller, recorder, data logger etc. without the need for special interfacing or signal conditioning. + Black (Blue) Power Supply Red + - + Black (Blue) Display/ Controller Display/ Controller USB PC N/C USB PC Model PU151 has 15:1 optics making it suitable for most applications. PU301 is specially designed for distant targets and has an optical resolution of 30:1. PUCF is designed for small targets and measures a spot size of o5mm at 100mm distance. All PyroUSB Series sensors are fully configurable from a PC using the CalexSoft software and USB cable supplied. This user friendly software enables the user to set the range and emissivity, compensate for reflected energy; apply filtering; select max, min, average or instantaneous readings; and peak or valley hold processing. These features can also be monitored and adjusted by an OPC Client. Other features include Data Acquisition, Alarms and a Scrolling Graphical Display. The sensor will operate with either the 4 to 20 mA cable connected, the USB cable connected, or both. The USB cable has an IP65 connector at the sensor end. An IP65 cap protects the sensor when the USB cable is not connected.

When assembled as shown the adjustable mounting bracket offers a rigid support for the sensor and allows fine adjustment in two planes. AIR PURGE COLLAR 25 mm diameter x 106.5 mm long Thread mounting M20 x 1 mm pitch Weight with Output Cable 175 g Output Cable Length 1m USB Cable Length 1m ENVIRONMENTAL Environmental Rating IP65 Ambient Temperature Range 0C to 70C Relative Humidity 95% max. non-condensing Sensor Voltage 6 V DC min Max Loop Impedance 900 Maximum Span 1000C Minimum Span 100C The air purge collar is used to keep dust, fumes, moisture and other contaminants away from the lens. Air flows into the fitting on the side and out of the aperture at the front. AIR/WATER COOLED HOUSING The air/water cooled housing allows the sensor to withstand ambient temperatures which exceed the normal 70C limit. Air or water (depending on the degree of cooling required) flows into one of the fittings on the side and out of the other. To prevent condensation forming on the lens, the air/water cooled housing is supplied complete with an air purge collar. Please note, the air/water cooled housing must be ordered with the sensor and cannot be fitted by the user. LASER SIGHTING TOOL The Laser Sighting Tool screws onto the front of the sensor during installation and indicates precisely where the sensor is aiming. Once the sensor has been aimed at the centre of the target and locked in position the Laser Sighting Tool can be removed. The laser is activated by means of a push button on the front of the tool which has a latching mechanism.
